Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
From airplanes to sailboats to bridges, composite materials have become a significant part of our everyday structures. With increasing demand, these materials are pushed to their limits to improve structural efficiency. As a consequence, research and devel ...
A new model for predicting the uniaxial stress-strain behavior of a unidirectional ceramic matrix composite, including stochastic matrix crack evolution, stochastic fiber damage, and ultimate failure, is presented. The model shows that (i) "brittle" behavi ...
The purpose of this thesis is to characterize internal strains in polymeric materials due to consolidation. In view of this, optical Fiber Bragg Grating sensors are an excellent non-destructive tool for internal strain characterization and damage detection ...

Aeroelastic tailoring requires structural compliance and thus often conflicts with stiffness requirements to carry prescribed aerodynamic loads. Recently however, the application of cellular structural concepts has suggested the potential to achieve compli ...
Nanocrystalline metals have been an area of great interest in recent years due to their enhanced characteristics. One of the most striking is implied by the Hall-Petch relation: with decreasing grain size the material becomes stronger. This promise is fulf ...
In composite processing, a compressible dry fiber preform is in many cases impregnated by a molten polymeric matrix. The impregnated part is sometimes used as produced, but most often it requires a reheating step before stamping, flow molding or even paint ...
Interface delamination during indentation of micron-scale ceramic coatings on metal substrates is modeled using discrete dislocation (DD) plasticity to elucidate the relationships between delamination, substrate plasticity, interface adhesion, elastic mism ...
In an effort to better understand the plasticity of tempered martensitic steels, uniaxial tension and compression tests were carried out. The temperature dependence of both the yield stress and the post-yield stress behavior were compared, and it was shown ...
In this paper, the behaviour of fibre Bragg grating sensors subjected to transversal as well as axial strains is characterized, both in the case of low-birefringent and polarization-maintaining single-mode optical fibres. Two configurations are considered. ...
